To all whom it may-concern: Be it knownthat 1, WILLIAM L. Borne, a citizen of the United States, residing at Kanand and useful Improvements in Explosive-Engines, of which the following is a specification.

My'invention relates to explosive engines :1; of the two cycle, reciprocating piston type and has for its object the provision of an en-' gine constructed so that both ends of the piston receive explosive impulses alternately and separate compression chambers are provided to supply the explosive mixture to the This 1 accomplish by providing an enlarged chamber in the central portion of the cylinder into which an extension of the upper-portion of thecylinder extends while the piston is pro-- vided with an annular offset and an up wardly projecting flange having gas-tight connections with the wall of the central enbeing the charge from the compression chamber to the 'ex losion chamber.

larged portion, the upper end of said central enlarged portion being connected with the carbureter and answers for the compression chamber for the explosion chamber formed by the lower end of the central enlarged portion'below the annular ofif-set of the piston aforesaid, the two chambers at the upper and lower ends of said central enlarged portion connected by a pipe so as to convey of the cylinder comprises another explosion chamber and is connected with a compression chamber located in the crank casing by means of another pi e.

My invention will be described in detail hereinafter and illustrated in the accompanying drawings in whichi Figure 1 is a central. vertical sectionalview of my improved engine, Fig. 2, a cross secintermediate the ends of pistonG The upper end ends which is secured to the top edge of offextending down into chamber D. v G indicates the piston slidably mounted in the cylinder and provided with the usual aching rings.

H indicates an annular ofl"'set or flange upwardly extending portion having packing rings secured thereto andgbearingagainst the wall of offset C. Ofiset H divides enlarged set C, the lower end, of the upper portion E andIan chamber D into two chambers, the chamber J being a compression chamber having connection by means of pipe K with a carbureter (not shown) for conveying the explosive gas thereto, while the chamber L, below offset H is an explosion chamber connected with chamber J by means of a pipe M. N indicatesa 'i exhaust'pipe for explosion arranged to. be opposite the delivery end of pipe it so as to cause the explosive charge flowinginto the chamber to be deflected upward and be more thoroughly distributed throughout the chamber.

chamber L. The crank casing B and the while the cham ing upwardly from the top of piston G and,

U indicates electric sparkers in the expioi sion chambers L and Q to fire the explosive charges at the proper time the operation of i this feature of the engine being understood l by persons skilled in. the art so that a detailed description thereof thought to be untion on the line :cac of Fig. 1, and Fig. 8, a necessary.

detail view of one form of check valve that I may be used'with my engine.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

The cylinder consists of a lower portion A which is formed as a continuation of the crank-casing B and provided with an off-set G forming an enlargedchamber D. The upper" end E of the cylinder is smaller in diameter than the lower'end A and with an annular/flange F intermediate of its provided ture and A check valve Vis provided in each pipe K and P to prevent the flow of the charge back to the carburetors, one form of valve being illustrated in Fig. 3 though any other l form may-be substituted therefor, the form sllilpwn being for the purpose of illustration tion it Willbe assumed L, O and Q are filled with the ex losive mm- For the purpose of description of the operathatthechambers J that an explosion has ta on place in chamber This will drive the'piston G downward compressing the gas in explosion chamber L and compression chamber until the outlet to exhaust S is reached when the burned gases in said chamber will escape therethrough more rapidly as the piston continuing theexhaust and finally uncovering the .mouth' ofpipe P allows the "explosive mixture in chamber O-t0 flow'into said chamber- Q and being diffused theretlirorugh by strik ing plate T 'itdrives out the ba ance of the burned gases; At the same time the suction created in chamber J draws the explosive mixture thereinto throu h. pipe K.

When the piston'reac es the extremity of its down-stroke the charge .in chamber -L is i exploded driving the piston G upward compressing the charge in explosive chamber'Q and the 'mixture in compression chamber J and drawing a fresh supply of the mixture into chamber 0 through pipe P. When the piston G has traveled upward far enough to expose the entrance to exhaust N the burned gases begin to escape and when the mouth of pipe M is exposed the compressed mixture in chamber J will pass thereinto forcing the remainder of the gases in chamber L out, the

trunk of piston G causing the explosive mixture to diffuse throughout the chamberso as to more thoroughly clear it of said burned gases. .When the extremity or the upward stroke of the piston G is reached the charge in chamber Q is again fired and the cycle us't described repeated.

Having thus described my invention what I claim 1s v p :1. In an explosive engine, a cylinder 'hav ing an enlarged offset intermediate of its ends a' piston-fitting the smaller hereof the cylinder, an annular 'ofl'set orflangeon the piston and a compression chamber at the other end thereof and connected with the explosion chamber aforesaid, and an explosion chamtofit the ofi'set'in the cylinder, an explosion v chamber at one end .Ofsaid enlarged offset to descend uncovers more of the entrance, to

her at one end of the smaller portion of the: cylinder and a compression chamber at the other end, the last'nam ed explosion and compression chambers being connected, substantlally as shown and descrrbed.

. 2. In anexplosive engine, a cylinder hav ing an enlar ed offset intermediate of its ends,- i

a piston fittlng the-smaller bore of the cylinder, an annular offset or'fiange intermediate of the ends of the piston, an upwardly extending portion .on said offset or flange fitting the bore of the offset to thecylinder, a pipe for delivering an explosive mixture tOthG chamber formed in one end-of the ofi'se't to the cylinder by the offset on the piston,.a pipe connecting said chamber with the charm her in the other end of the offset,a pipe for delivering an explosive mixture to the chamber in the cylinder at one endof thepiston,

and a pipe connecting thechambers atcthe two ends of the cylinder, substantially as shown and described.

' 'In'testimony whereof I hereto aflix my signature invthe presenceof two witnesses. 7
